The disadvantage of using one of these devices is that you are stuck with a fixed current. You might very well find that it and an is an advantage to be able to vary the amount of current according to the surface area of the silver wire that you have immersed in water. You can do this easily by dividing the voltage available by the current that you desire and purchase a resistor for the resulting value. Resistors are available at any radio shack for 99ยข for five. For instance, if you did want one milliamp and you had say, 27 volts (3-9 volt batteries) then you would divide 27 by 0.001. The result would be 27,000. So you would insert a 27 K resistor in series and you would have a limit of one milliamp. For a discussion of the advantage of using even lower values for current vs. surface area, have a look at this link.

It adjust voltage to maintain mill amp rating. You can use even a low voltage power supply, it will just take longer. I have a 9 volt power supply that puts out 9 volts at 800 mill amps, at 1 mill amp it puts out close to 23 volts. So if you read the voltage at no load with a multi meter (I mill amp is close to no load). Once you have a batch you can seed the next batch to save time. Bob
